Quiescent Volcano—Chest Wall Hemangioma

Chest wall hemangiomas are rare tumors that may originate within the soft tissue or from the ribs. Intramuscular hemangioma is infrequent, representing less than 1 % of all hemangiomas, and the localization in the chest wall is even less frequent. They are typically cutaneous in location, large, and poorly circumscribed and can be locally destructive. We present a case of a 34-year-old lady presented with firm lump 3 × 3 cm in left upper and inner quadrant of left breast well defined borders, non-pulsatile and restricted mobility. Sono-mammogram was suggestive of ill-defined lesion at 10 o’clock position. CT chest was conclusive of chest wall hemangioma. The patient underwent excision of the lump. HPE was suggestive of cavernous hemangioma. Cavernous hemangioma typically manifest at birth or before the age of 30 years. CT is more sensitive than plain radiography in detecting phleboliths, which are present in approximately 30 % of cavernous hemangiomas. Surgical excision would be treatment of choice. In this case, the site of the lesion was in the breast clinically mimicking that of a fibroadenoma which warrants hemangioma as a differential diagnosis.     

Toxicity profile of repeated doses of PEG‐asparaginase incorporated into a pediatric‐type regimen for adult acute lymphoblastic leukemia

Despite having been long regarded as too toxic for adult patients, pediatric‐like regimens containing L‐asparaginase have resulted in improved outcomes for adults with acute lymphoblastic leukemia (ALL). To characterize the spectrum of toxicity of repeated doses of polyethylene glycolated‐asparaginase (PEG‐asp) in adults, we reviewed all doses (2000 IU/m²) administered as part of a pediatric‐inspired regimen in adult ALL at our center. Subjects aged 18–60 yr with ALL (n = 152, 69.1% male) contributed 522 dose cycles to the study. Hepatotoxicity was the most common adverse event: grades 3–4 transaminitis and hyperbilirubinemia occurred in 53.9% and 23.7% of subjects, respectively. Hepatotoxicity was reversible; no cases of fulminate hepatic failure were observed. Other toxicities affecting at least 5% of subjects were grades 3–4 triglyceridemia in 50.9%, hypofibrinogenemia (<100 mg/dL) in 47.9%, clinical pancreatitis in 12.6%, venous thromboembolism in 11.2%, allergic reaction in 7.2%, and any grade bleeding in 5.3%. PEG‐asp was always discontinued after grades 3–4 pancreatitis or allergic reaction. Otherwise, toxicities did not preclude administration of additional cycles of the drug. Our results suggest that repeated PEG‐asp dosing is safe in adults aged 18–60 yr, even after occurrence of a drug‐related toxicity.

Biopotential of secondary metabolites isolated from marine sponge Dendrilla nigra

ObjectiveTo evaluate the biopotential activity of secondary metabolites from marine sponge Dendrilla nigra (D. nigra) collected from the Gulf of Mannar. Objective: Soxhlet extraction method was used to extract the secondary metabolites and various assays were carried out.ResultsD. nigra showed potent antibacterial, antioxidant, anti-inflammatory and anticancer activities and it was also subjected for brine shrimp lethality and cytotoxicity assays. The secondary metabolites were characterized by gas chromatography-mass spectrometry (GC-MS) analysis.ConclusionsBased on the present study, it can be inferred that the bioassay guided fractionation and purification of D. nigra may come up with potent bioactive drug.     

Relationship between arterial dysfunction and extra-articular features in patients with rheumatoid arthritis

Systemic inflammation may be a common process that underpins both atherosclerosis and extra-articular features (ExRA) of rheumatoid arthritis (RA). We evaluated the relationship between ExRA and arterial dysfunction in 114 consecutive patients with RA (82% women) without overt arterial disease aged 40–65?years. A trained research nurse undertook ‘SphygmoCor’ pulse wave analysis (PWA) using radial applanation tonometry to measure the extent (augmentation index, AIX%) and timing (reflected wave transit time, RWT, msec) of aortic wave reflection. Assessment included fasting blood sample, patient questionnaire and medical record review. Mean differences were adjusted for age, sex, mean blood pressure, smoking pack-years, fasting cholesterol, Stanford HAQ score and erythrocyte sedimentation rate. Mean age was 54 (SD 7) and median RA duration 10 (IQR 4–17) years. There was a trend for arterial dysfunction (higher AIX%; lower RWT) to increase as the number of ExRA features rose, but no difference in AIX% (?0.5, 95%CI ?2.8 to 1.8, P?=?0.65) or RWT (0.3?ms, 95%CI ?3.6 to 4.2, P?=?0.86) between ‘any ExRA’ and ‘no ExRA’. Arterial dysfunction was not associated with the presence of rheumatoid nodules, Sjogren’s syndrome or carpal tunnel syndrome. Our study was too small to determine whether severe (‘Malmo’) ExRA (vasculitis, pericarditis, episcleritis) was truly associated with a higher AIX% (3.8, 95%CI ?2.3 to 9.9, P?=?0.22) and lower RWT (?5.5?ms 95%CI ?13.1 to 2.1, P?=?0.16). While arterial dysfunction may be associated with the number of ExRA features and severe ExRA, it does not appear to be associated with other ExRA features.     

Different Pharmaceutical Products Need Similar Terminology

In the last decade, discussions on the development of the regulatory framework of generic versions of complex drugs such as biologicals and non-biological complex drugs have attracted broad attention. The terminology used is far from harmonized and can lead to multiple interpretations of legal texts, reflection papers, and guidance documents regarding market introduction as well as reimbursement. This article describes the meaning of relevant terms in different global regions (Europe, USA, WHO) and offers a proposal for a globally accepted terminology regarding (non-) biological complex drugs.     

Intestinal microbiota and its association with colon cancer and red/processed meat consumption

The human colon harbors a high number of microorganisms that were reported to play a crucial role in colorectal carcinogenesis. In the recent decade, molecular detection and metabolomic techniques have expanded our knowledge on the role of specific microbial species in promoting tumorigenesis. In this study, we reviewed the association between microbial dysbiosis and colorectal carcinoma (CRC). Various microbial species and their association with colorectal tumorigenesis and red/processed meat consumption have been reviewed. The literature demonstrated a significant abundance of Fusobacterium nucleatum, Streptococcus bovis/gallolyticus, Escherichia coli, and Bacteroides fragilis in patients with adenoma or adenocarcinoma compared to healthy individuals. The mechanisms in which each organism was postulated to promote colon carcinogenesis were collated and summarized in this review. These include the microorganisms' ability to adhere to colon cells; modulate the inhibition of tumor suppressor genes, the activations of oncogenes, and genotoxicity; and activate downstream targets responsible for angiogenesis. The role of these microorganisms in conjugation with meat components including N‐nitroso compounds, heterocyclic amines, and heme was also evident in multiple studies. The outcome of this review supports the role of red meat consumption in modulating CRC progression and the possibility of gut microbiome influencing the relationship between CRC and diet. The study also demonstrates that microbiota analysis could potentially complement existing screening methods when detecting colonic lesions.
